The R-302 MP5 Top Rail allows the user to attach optics to the MP5. The rail has a smooth design for ease of handling and higher repeatability. Made from a single billet of 7975 T651 aluminum and hard coat anodized. Fits H&K MP5 and most MP5 clone weapons. Chosen by the German National Police as part of their MP5 upgrade program in late 2019.
Finish is a bit on the shiny side. Matches HK black Duracoat.
